MACHINE FOR SETTING COP-TUBES ON MULE-SPINDL/ES, 86C.

SPECIFICATION forming part of Letters Patent No. 245,339, dated August9, 1881.

Application filed February 3, 1851.

To all whom t may concern:

Be it known that I, JOSEPH A. BARBER, a citizen 0f the United States,residing at Holyoke, in the county of Hampden and State ofMassachusetts, have invented new and useful Improvements in Machines forSetting' Cop-iv Tubes on Mule-Spin'dles and upon the spindles of othersimilar machines, of which the following is a specification.

This invention relates to the details ot' construction of a machine forgrasping simultaneously a series of cop-tubes near their bases, and fordrawing said tubes completely onto their spindles, the object being toenable an operative to rapidly and regularly set cop-tubes upon thespindles, setting the whole series at a uniform height by one movementofthe machine, therebysavingmuch time over the usual method of setting`one tube at atime separately.

In the drawings forming a part ot' this specification, Figure lis a planview with the pressure-plate of the machine removed and with thecop-tube clamps standing open. Fig. 2 is a rear elevation of themachine, partly in section and Fig. 3 represents a series of spindles,looking from the machine toward the back side of the spindles, and afront elevation of the machine, showing the tube-clamps closed upon thetubes and in the position in which the invention will be found after themachine has drawn thetubes onto the spindles ready to be disengaged fromthem.

In the drawings, A is the frame. B is the pressure-plate. ce arespring-sockets pending fromthe under side of the pressure-plate B. e eare triangular slide-blocks, pending also from the under surface of saidpressure-plate. fi i are spiral springs in tube-sockets c c. 0 o', aretwo horizontal slide-bars. s s are slide-bar guide-posts. t e aretube-clamps pivoted on frame A, the straight ends of which enteropenings a: in the slide-bars o and o. 2 2 are spiral springs, one endof which is attached to an arm, 3 8, projecting from the slide-bars oo', and the other ends of said springs are attached to the bottom offrame A. Two arms, 4 4, project horizontally from said slide-bars underthe diagonal face ofthe blocks e e on the under side of pressure-plateB. The slide-bar guide-posts s s are secured to the base of frame A, andtwo other posts, 5 5, stand likewise upon (No model.)

said frame under the lower ends of the springsockets c c, beneath thespiral springs therein.

Two other posts, G G, are xed on frame A,

which serve to guide the vertical motion of the pressure-plate B, whoseends are pierced to pass over said posts. Screw-supports 7 are fixedupon each end of frame A, into which two adjusting-screws, S, areplaced, as shown. 9 are spindles. l0 are cop-tubes. l l is a spin-(lle-rail.

The slide-bars o o" are fitted to slide horizontally in oppositedirections in the slide-bar guide-posts s sv on frame A, actuated by thecontact of the slide-blocks e e with the arms 4 4, when thepressure-plate is moved backward; and springs 2 2 serve to draw the bars0 0 back to their starting-points, wheny the action of thepressure-plate ceases by its being allowed to rise. The spiral springsin the spring-sockets c o lift the pressure-plate away from the frame A,when said plate is left free to rise. The said slide-bars 0 0 arearranged on different horizontal lines in the rear of the tube-clamps,because the top half of those clamps is higher than the lower half, thearm of the top half entering the upper bar, and that of the lower halfentering the lower bar; consequently, when the said slide-bars are.moved, as they are, in opposite directions by the downward movement ofthe pressure-plate B, they cause the clamps to be closed; and when thepressure-plate rises, the clamps open by the reverse action of theclamp-bars, caused by the said springs 2 2.

rlhe operation of my machine in setting coptubes is as follows: Anoperator passes along in front ofthe spindles on the machine, passingthe lower end of the cop-tubes just over the top end of the spindles.That operator is followed by another one, carrying this machine, whichmay be arranged with a sufficient number of clamps to operate upon anyconvenient number of spindles, the clamps being in the position shown inFig. l, and places it in a position to bring the lower portion of thetubes which have been placed upon the spindles within the clamp-jaws,when he forces down the pressure-plate B, causing said clampjaws to shutup upon the tubes. The operator then brings the machine down toward thespindle-rail 11, carrying the tubes, with the ina- IOO chine, down tothe position seen in Fig. 3, when he lets the pressure-plate B rise up,causing the clamps to be opened, and moves the machine along, and inlike manner grasping another series of tubes and sliding them alldownsimultaneouslyontothe spindles. When the machine is moved down todraw the tubes onto the spindles, the adjusting-screws S, set in eachend of the machine, strike the rail 1l and determine the height to whichthe tubes are drawn upon the spindles.

By the use of this machine, as just described, very much time is savedin setting cop-tubes upon mule-spindles, for by the ordinary method anoperative draws one tube at a time upon the spindle, regardless of anyprecise method for determining a uniform height for all the tubes, andconsequently the winding of the yarn thereupon is not uniform relativeto their ends, as it should be; but by using this machine a series often or fifteen tubes can be set simultaneously as quickly as anoperative can set one tube. They are all placed uniformly upon thespindles, as seen in Fig. 3, and the inconveniences resulting fromsetting tubes singly are all obviated.

It is obvious that this machine may be constructed with one side of theclamp-jaws fixed and the other side movable by like devices to thoseshown inthe drawings; butto obtain ease and uniform action in theslide-bars and press ure-plate it is preferable to construct the machineas herein shown.

That I claim as my invention is?A Ll. In a machine for setting cop-tubesonto spindles, the combination, with a series of pivoted tube-clam ps,fv, ofthe perforated slide-bars o o', having the arms 4 4 thereon, thesprings 2 2, and the pressure-plate B, having the triangular blocks ethereon, and of appliances, substantially as described, for lifting saidpressure-plate, substantially as fet forth.

2. The combination, with the series of pivoted tube-clamps o and case A,and with appliances, substantially as described, for closing and openingsaid clamps, of the adjustingscrews S in each end of said frame,substantiall y as and for the purpose set forth.
